Advanced Features

My Cloud EX4 comes complete with a full suite of advanced features to power your home or office.

Volume virtualization using iSCSI targets

Manage storage over long distances and transfer data over LANs, WANs or the Internet by creating a Storage Area Network (SAN). My Cloud EX4 allows you to create and manage iSCSI targets, similar to a local hard disk drive, that is accessed over a network rather than locally. The iSCSI target is protected by the underlying RAID structure of the My Cloud EX4 server.

Jumbo frame support

My Cloud EX4 supports jumbo frames up to 9000 bytes. These large IP frames are used to increase performance over supported networks. Increases in data transfer speeds only occur if every device on your network supports jumbo frames.

Link aggregation and failover support

Combine multiple network connections to increase data transfer past a single connection and provide redundancy in the event of a failed connection. This is also known as bonding, and refers to the use of two LAN NICs present in your NAS and two cables connected to your router simultaneously, improving reliability.
